The V-PASS

The V-PASS is similar to the VeriProx and VeriFlex, but no Wiegand input device

is required. The V-PASS will automatically detect when a finger is placed on the

sensor, compare that fingerprint with all currently enrolled fingerprint templates

and determine if there is a match. A typical operation is described below.

• The V-PASS top LED is yellow to indicate it is ready for a finger.

• A user initiates the action by placing their finger on the fingerprint sensor.

• The User should place the correct finger on the scanner using the Bioscrypt

Ridgelock.

• The V-PASS will recognize that a finger has been placed and will take an

image of that finger’s print.

• The amber light will turn off, signaling that the image has been scanned and

the finger can be removed.

• The scanned image is compared with ALL enrolled templates in the

memory of the V-PASS (maximum of 200).

o If the verification is positive, the top LED will glow green and the unit

will emit an audible beep.

o If the authentication fails, the LED will glow red and no beep will be

generated.

• When authentication is successful a Wiegand string can optionally be sent

out for use by a standard door controller.

The V-PASS has several communication options. It is equipped with both a Host

port and an auxiliary port. The Host port may be configured to operate in RS-232

mode or RS-485 mode. The auxiliary port is always set to RS-232. The Host port

connections are made through the wiring pigtail on the back of the reader. The

auxiliary port is accessed from an RJ-11 jack that is hidden under a door on the

bottom of the V-PASS. This door is held shut with a security screw.

The V-PASS can be used as a stand-alone reader or multiple units can be

configured on an RS-485 network. The manner in which you choose to install the

V-PASS will determine which communications settings are most convenient for

your configuration. Certain administrative functions are common to any

installation. You must have a way to “enroll” users into the system, that is, you

must be able to associate their fingerprint data with a specific Wiegand ID number.

You must have a way to distribute this user information to all other readers in your

installation. The VeriAdmin Management Software is provided for this purpose.
